Sabotaged Boat

August 9, 1985

PARIS — The French government will investigate reports that its secret service sank the Greenpeace ecology group's boat Rainbow Warrior in Auckland, New Zealand. The vessel's destination: The French nuclear testing grounds in the South Pacific. Two explosions blew holes in the Rainbow Warrior's hull July 10 and killed a member of the Greenpeace staff. President Francois Mitterrand ordered ''a rigorous inquiry'' and Prime Minister Laurent Fabius Thursday appointed a special investigator, Bernard Tricot, a government official under Charles de Gaulle.
